StackX Backup is the StackX product for managed backup servers and receivers.
It standardizes and automates backup ingestion, verification, protection, and restoration through a hardened, monitored baseline designed for production operations.
It should not be confused with the backup option included in some managed services: that option may use StackX Backup components internally, but it remains a feature of the subscribed service.
PBS backup is also separate: it protects ScalarCloud VMs at the infrastructure level. On ScalarCloud Public, billed storage already includes the associated PBS backup. In Private Cloud, PBS is attached to the client’s dedicated architecture.
What StackX Backup Provides

|---|
| ScalarCloud Public PBS backup | VM backup included with ScalarCloud Public storage billed per GB |

| Private Cloud PBS backup | VM backup attached to the client’s dedicated private cloud architecture |

Usage Models
Usage Models| Model | Use |
|---|
| Internal ScalarX baseline | Component used to operate backups included with selected managed services |

| ScalarCloud complement | Application backup in addition to PBS VM backups when operations justify it |
|---|
Security and OperationsAccess, forced commands, and operational checks
